it sometimes is hard to completely stop doing something that is a habit in just a single day

it all depends on the person and if they feel you really mean it or that it's very important to you, well if that really matters to him

though you said texting not calling right?
it may also be something he won't change so if he doesn't... you may have to accept it

I've seen how addicting it is for people to stop texting I have a hard time prying my little sister away from texting
she hoards our parent's phones and for example she was texting all day yesterday first on the phones which mom had left one on the charger because it was almost dead and then so my other sister could use it later, but we left and my youngest sister had both phones with her, very clingy to them
then later when the phones were dead due to not being charged properly she was on her kindle fire texting with an app... people tried talking to her and no one seemed to get through to her, just said her name over and over again till we gave up and a bit later she was like wha!?

-_-;

it takes time and patience sometimes
